MCP Self-Learning Server

Implementation Reference

• mcp-self-learning-server.js:1303-1325 (handler)

  The core handler function that implements the get_performance_metrics tool. It extracts metrics from the learning engine, applies time range filtering (placeholder), computes detailed tool usage and error breakdowns, and includes recommendations.

  async handleGetPerformanceMetrics(args) {
    const { timeRange = 'all' } = args;
    const metrics = { ...this.learningEngine.metrics };
    
    // Filter by time range if needed
    if (timeRange !== 'all') {
      // In production, would filter based on actual timestamps
      metrics.timeRange = timeRange;
    }
    
    // Add detailed breakdowns
    metrics.toolBreakdown = Array.from(metrics.toolUsageFrequency.entries())
      .map(([tool, count]) => ({ tool, count, percentage: (count / metrics.totalInteractions * 100).toFixed(2) }));
    
    metrics.errorBreakdown = Array.from(metrics.errorPatterns.entries())
      .map(([error, count]) => ({ error, count }));
    
    return {
      success: true,
      metrics,
      recommendations: this.learningEngine.generateGlobalRecommendations()
    };
  }

• mcp-self-learning-server.js:1045-1054 (schema)

  Input schema defining the parameters for the tool, specifically an optional 'timeRange' with allowed values.

  inputSchema: {
    type: 'object',
    properties: {
      timeRange: {
        type: 'string',
        enum: ['hour', 'day', 'week', 'all'],
        default: 'all'
      }
    }
  }

• mcp-self-learning-server.js:1042-1055 (registration)

  Tool registration in the MCP server's tools array, specifying name, description, and input schema for MCP discovery.

  {
    name: 'get_performance_metrics',
    description: 'Get detailed performance metrics',
    inputSchema: {
      type: 'object',
      properties: {
        timeRange: {
          type: 'string',
          enum: ['hour', 'day', 'week', 'all'],
          default: 'all'
        }
      }
    }
  }

• mcp-self-learning-server.js:1098-1100 (registration)

  Dispatch case in the MCP tool request handler that routes calls to get_performance_metrics to its handler function.

  case 'get_performance_metrics':
    result = await this.handleGetPerformanceMetrics(args);
    break;
